Defines the available matching uid and gid range for which the backend is authoritative.

script

This option can be used to configure an external program for performing id mappings instead of using the tdb counter. The mappings are then stored int tdb2 idmap database. For details see the section on Idmap Script below.

The tdb2 idmap backend supports an external program for performing id mappings through the smb.conf option idmap config * : script or its deprecated legacy form idmap : script.

The mappings obtained by the script are then stored in the idmap tdb2 database instead of mappings created by the incrementing id counters. It is therefore important that the script covers the complete range of SIDs that can be passed in for SID to Unix ID mapping, since otherwise SIDs unmapped by the script might get mapped to IDs that had previously been mapped by the script.

The script should accept the following command line options.

SIDTOID S-1-xxxx
IDTOSID UID xxxx
IDTOSID GID xxxx

And it should return one of the following responses as a single line of text.
